That is the mid point or flat point of the precision wire-wound potentiometer range. Firmware won't do anything. You not dealing with a linear digital application, this is true analog implementation, and when used with the remote you will always notice a bit of jumping of volume level as displayed when turning the motorized potentiometer in the flat point.
Does this help?
Is this behavior expected to be consistent no matter which direction the volume is being adjusted? I wouldn't expect a firmware update to address the properties and behavior of an analog/"physical" device, but if there is an issue with the digital display of the current status of the analog physical device as is the case here, then it *could* be a firmware thing I think, I dunno, I have a lot of reading and testing yet to do .
P.S. by consistent I mean that the "jumping" will be consistent in the flat points (i.e. that going from -12->-12.5 should always have the same size jump), and therefore *potentially* the position of the volume knob should always be consistent with a certain volume setting assuming the physical volume control position is synchronized with the volume level indication. I am not meaning that the size of the jumps will be consistent across the range of adjustment. If volume knob position does not correlate to true volume level, then I think having the little value indication hash mark on the volume knob is misleading, it should just be a faceless knob like most of my other gear, THAT could also fix it .
